Sewage feature evaluating and insulator equipping method for coastal areas

Abstract

The invention discloses a sewage feature evaluating and insulator equipping method for coastal areas. The method comprises the following steps: firstly judging whether an area to be measured is a coastal area or not according to the field salinity and salinity threshold value of the area to be measured; when salinity measurement conditions are lacked, judging the distance between the area to be measured and a coastline according to topographical parameters of the area to be measured, so as to judge whether the area to be measured is the coastal area or not; judging whether the area to be measured is an urban or industrial area according to the distance between the area to be measured and the urban area or a pollution source; judging whether the area to be measured is a mountain forest or cultivation area according to the distance between the area to be measured and a forest region or a farmland; judging whether the area to be measured is a river or a lake land according to the distance between the area to be measured and a water area; and equipping insulators according to evaluation results. The method provided by the invention is applied to practical engineering, sewage features can be quickly estimated according to geographic features when external insulation work is carried out in areas lacking equivalent salt deposit density data, and then the types and insulation levels of the insulators are quickly determined.

Description

technical field [0001] The invention belongs to the technical field of pollution and wet characteristic evaluation, and more specifically relates to a pollution and wet characteristic evaluation and an insulator allocation method for coastal areas. Background technique [0002] The commonly used methods for judging the degree of pollution on the transmission line include the salt / ash density measurement method and the pollution and humidity characteristic estimation method. It is a method required by the national standard to measure the salt / dust density of the dirty sample of the insulator. However, because the measurement of dirty salt / dust density on the insulator surface requires professional sampling work and salt / dust density measurement equipment in a laboratory environment, the conditions are relatively harsh and the measurement cycle is long. Therefore, estimation methods are often used to determine the degree of pollution under site conditions; that is, based on o...
